1. Chapter 2 Hardware

2. Learning Objectives Upon successful completion of this chapter, you will be able to: describe information systems hardware; identify the primary components of a computer and the functions they perform; explain the effect of the commoditization of the personal computer

3. Hardware Defined Digital devices that you can touch: – Desktop computers – Laptop computers – Mobile phones – Tablets – E-readers – Storage devices such as USB drives – Input devices such as keyboard, mouse, scanners, or stylus – Output devices such as printers and speakers Digital devices process electronic signals in 1’s and 0’s – The physical parts of a computing device

4. Understanding Binary Binary:

5. Moore’s Law The number of transistors on a chip will double every 2 years. Or…The amount of computing power will double every 2 years.

6. PC Components Components of a PC: Circuit board – also known as the motherboard that holds the CPU, memory, and storage components CPU (central processing unit) – carries out the commands sent to it by the software and returns results – Faster is better Memory – temporary working area called random- access memory (RAM) – Applications are loaded into RAM to run faster – When computer is powered off, the RAM is cleared – Bigger is better

7. Chapter 2: Hardware Removable Media Hard Disk and Solid State Drives Case with Wiring Sound Card Power Supply Graphics Card Radiator and Cooling Fans RAM CPU and Water Block Motherboard

8. PC Components continued Storage – longer, permanent storage of data – Hard disk – permanently affixed to motherboard using cables??? – Removable media – USB drives that can be connected and removed for use on a different computer – Bigger and faster is best Input/output devices – allows the addition of devices for input and output purposes via ports on the motherboard or today by USB – Keyboard for entering data – Printer for printing output

9. Other Computing Devices Portable computers Smartphones Tablets Mobile devices such as fitness trackers Medical devices such as a pacemaker/defibrillator Everyday items – the Internet of Things

10. Types of Wiring Wire Type – Port Type – Connected Event o CAT5 – Ethernet Port – Network/Internet to Computer o Serial ATA – SATA Port – Motherboard to Disk Drives o USB Cable – USB Port – Peripherals to Computer o HDMI – HDMI Port – High quality graphic displays (Monitors) to Computer

11. Sidebar: How can I make my computer fast? RAM (Random-access Memory) CPU (Central Processing Unit)

12. Other Computing Devices Portable Computers Smartphones Tablet Computers Mobile Devices Integrated Computing Transportation: Cars/Planes/Motorcycles Appliances: Refrigerator/Thermostats

13. Wired and Wireless Connectivity Wired devices have limited mobility because they must be directly connected via a wire to the network (either a closed network or the internet) Wireless devices have portable connectivity when paired with services like 3G/4G or Wi-fi

14. Commoditization of the Personal Computer PC is a commodity – Little differentiation between computers. – Primary factor that controls their sale is the price. – Hundreds of manufacturers world-wide create parts for personal computers. – Low profit margins on PCs push manufacturers to seek the lowest-cost manufacturing. Apple – No open standards. – Unique product, not easily copied. – Apple can charge more. – Differentiation strategy. (more in Chapter 7.)

15. Cloud Computing Makes powerful portable computing possible by utilizing cloud services Cloud services remove the burden of storage and operational ability from your device Potential for security issues as your documents are stored on a server

16. E-Waste What is it? o Cell phones o Remote Controls o Cables and Wires o Cartridge Games o Consumer Electronics Hazardous Waste

17. E-Waste Continued Who is it hurting? o Effects on Global Communities What do we do with it? Where do we recycle? o www.epa.gov o www.earthday.org

18. Summary Described different types of hardware (more in networking); Showed the primary components of a computer and the functions they perform; Explained the effect of the commoditization of the personal computer.
